[Android.Runtime.Register("newFileSystem", "(Ljava/net/URI;Ljava/util/Map;)Ljava/nio/file/FileSystem;", "", ApiSince=26)]
public static Java.Nio.FileNio.FileSystem? NewFileSystem (Java.Net.URI? uri, System.Collections.Generic.IDictionary<string,object>? env);
[<Android.Runtime.Register("newFileSystem", "(Ljava/net/URI;Ljava/util/Map;)Ljava/nio/file/FileSystem;", "", ApiSince=26)>]
static member NewFileSystem : Java.Net.URI * System.Collections.Generic.IDictionary<string, obj> -> Java.Nio.FileNio.FileSystem

Parameters

uri
URI

the URI identifying the file system

env
IDictionary<String,Object>

a map of provider specific properties to configure the file system; may be empty

Returns

a new file system

Attributes

Remarks

Constructs a new file system that is identified by a URI

This method iterates over the FileSystemProvider#installedProviders() installed providers to locate the provider that is identified by the URI URI#getScheme scheme of the given URI. URI schemes are compared without regard to case. The exact form of the URI is highly provider dependent. If found, the provider's FileSystemProvider#newFileSystem(URI,Map) newFileSystem(URI,Map) method is invoked to construct the new file system.

Once a file system is FileSystem#close closed it is provider-dependent if the provider allows a new file system to be created with the same URI as a file system it previously created.

<b>Usage Example:</b> Suppose there is a provider identified by the scheme "memory" installed:

Map&lt;String,String&gt; env = new HashMap&lt;&gt;();
              env.put("capacity", "16G");
              env.put("blockSize", "4k");
              FileSystem fs = FileSystems.newFileSystem(URI.create("memory:///?name=logfs"), env);

NewFileSystem(IPath, ClassLoader)

Constructs a new FileSystem to access the contents of a file as a file system.

[Android.Runtime.Register("newFileSystem", "(Ljava/nio/file/Path;Ljava/lang/ClassLoader;)Ljava/nio/file/FileSystem;", "", ApiSince=26)]
public static Java.Nio.FileNio.FileSystem? NewFileSystem (Java.Nio.FileNio.IPath? path, Java.Lang.ClassLoader? loader);
[<Android.Runtime.Register("newFileSystem", "(Ljava/nio/file/Path;Ljava/lang/ClassLoader;)Ljava/nio/file/FileSystem;", "", ApiSince=26)>]
static member NewFileSystem : Java.Nio.FileNio.IPath * Java.Lang.ClassLoader -> Java.Nio.FileNio.FileSystem

Parameters

path
IPath

the path to the file

loader
ClassLoader

the class loader to locate the provider or null to only attempt to locate an installed provider

Returns

a new file system

Attributes

Remarks

Constructs a new FileSystem to access the contents of a file as a file system.

This method makes use of specialized providers that create pseudo file systems where the contents of one or more files is treated as a file system.

This method iterates over the FileSystemProvider#installedProviders() installed providers. It invokes, in turn, each provider's FileSystemProvider#newFileSystem(Path,Map) newFileSystem(Path,Map) method with an empty map. If a provider returns a file system then the iteration terminates and the file system is returned. If none of the installed providers return a FileSystem then an attempt is made to locate the provider using the given class loader. If a provider returns a file system then the lookup terminates and the file system is returned.

Constructs a new file system that is identified by a URI

[Android.Runtime.Register("newFileSystem", "(Ljava/net/URI;Ljava/util/Map;Ljava/lang/ClassLoader;)Ljava/nio/file/FileSystem;", "", ApiSince=26)]
public static Java.Nio.FileNio.FileSystem? NewFileSystem (Java.Net.URI? uri, System.Collections.Generic.IDictionary<string,object>? env, Java.Lang.ClassLoader? loader);

static member NewFileSystem : Java.Net.URI * System.Collections.Generic.IDictionary<string, obj> * Java.Lang.ClassLoader -> Java.Nio.FileNio.FileSystem

Parameters

uri
URI

the URI identifying the file system

env
IDictionary<String,Object>

a map of provider specific properties to configure the file system; may be empty

loader
ClassLoader

the class loader to locate the provider or null to only attempt to locate an installed provider

Returns

a new file system

Attributes

Remarks

Constructs a new file system that is identified by a URI

This method first attempts to locate an installed provider in exactly the same manner as the #newFileSystem(URI,Map) newFileSystem(URI,Map) method. If none of the installed providers support the URI scheme then an attempt is made to locate the provider using the given class loader. If a provider supporting the URI scheme is located then its FileSystemProvider#newFileSystem(URI,Map) newFileSystem(URI,Map) is invoked to construct the new file system.
